Bank One Ballpark is a stadium located in Phoenix, Arizona. It is across the street from the America West Arena, used by the Phoenix Suns.
Bank One Ballpark's main concern is with baseball, being home of the Major League Baseball's Arizona Diamondbacks. The park began to be constructed in 1996, and was finished just before the Diamondbacks' first season began, in 1998. It has a retractable roof, one of only a few stadiums in the United States to have one (others are in Houston, Texas, Seattle, Washington and Milwaukee, Wisconsin, with another under construction in the Phoenix suburb of Glendale). It also has a swimming pool, which is rented to patrons.
In 2001, the park saw a historical moment happen, when the Diamondbacks won Game 7 of the World Series against the New York Yankees. Down two runs to one and with one out in the bottom of the ninth, Tony Womack ripped a double down the right field line of Yankees super-closer Mariano Rivera, scoring Midre Cummings to tie the game at two. After Craig Counsell was hit by a pitch, Luis Gonzalez hit a single that scored Jay Bell, giving the Diamondbacks the world championship and putting a screeching halt to the Yankee dynasty.
Bank One Ballpark is named after Bank One of Chicago, Illinois and also is host to many concerts and other sports events each year. One of the events it holds annually is the Insight Bowl, a college football bowl game.
